MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200DTBDG1A DS200DTBDG1ABB terminal board connects field wiring to Mark V control systems. This board provides a reliable interface between field devices and I/O modules. You will find this terminal board in Speedtronic Mark V control cabinets and panels. Its high-density design accommodates forty field wiring points.
Termination Architecture
This terminal board provides forty screw terminal connections for field wiring. Consequently, you can connect many sensors without additional terminal blocks. The GE DS200DTBDG1A DS200DTBDG1ABB supports both analog and digital field devices. Moreover, each terminal includes a clearly marked identification number. You can terminate wires quickly using standard slotted screwdrivers.

Field Wiring and Terminal Design
The unit uses high-quality screw clamp terminals for reliable connections. Therefore, wires stay secure even under vibration from turbine operation. This board replaces the DS200DTBDG1ABB version without any wiring changes. Simply remove the old board and install this one. GE designed this terminal board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Four PCB layers separate field wiring traces from backplane signals. Two connectors handle all signal and ground connections. The GE DS200DTBDG1A DS200DTBDG1ABB includes a dedicated ground bar for cable shields. Accordingly, you can terminate shield wires without additional hardware. This feature improves noise immunity in electrically noisy turbine environments.
Installation and Wiring Guide
You can terminate both stranded and solid copper wires easily. The screw clamps accept wires without special ferrules or lugs. The GE DS200DTBDG1A DS200DTBDG1ABB works with all GE Mark V I/O modules. Always strip 6-8 mm of insulation before inserting wires. Proper torque on terminal screws prevents loose connections over time.
Each terminal position corresponds directly to a specific I/O channel. The board includes two configuration jumpers for signal type selection. The GE DS200DTBDG1A DS200DTBDG1ABB simplifies field wiring for turbine systems. Installation requires only a flathead screwdriver for terminal connections. This board operates reliably in non-condensing environments with adequate clearance.
